The busiest day of the year for Ontario heating technicians is the first night temperatures drop below zero. Running a test cycle on a mild afternoon lets you catch worn igniters or airflow issues early.

1. Run a 15-Minute Heat Test Cycle Now

Switch your thermostat to Heat and set it 3 degrees above room temperature. Within three to five minutes, warm air should flow steadily from your supply registers without metallic clicking or burning odours.

2. Replace the Furnace Air Filter

A clogged air filter restricts return airflow, causing the heat exchanger to overheat and trip the high-limit safety switch.

3. Clear Exterior PVC Intake and Exhaust Vents

Walk outside and inspect the white PVC furnace flue pipes on the side of your home. Remove leaves, wasps nests, or debris that could block combustion airflow and trip the pressure switch.

4. Check the Condensate Drain Line

High-efficiency condensing furnaces produce water while heating. Make sure the clear vinyl drain tube flowing to your floor drain or condensate pump is free of kinks and slime buildup.

5. Book an Annual TSSA Safety Tune-Up

A licensed technician measures carbon monoxide levels, cleans the flame sensor, tests capacitor microfarads, and verifies gas manifold pressure so your system runs reliably all winter.
